Wet Oxidation Equipment-TIANS Engineering Technology Group

Introduction

High Speed Response, Pioneer in Environmental Protection

The pipeline flow oxidation sewage treatment equipment is an independently developed sewage treatment equipment by TIANS based on Fenton oxidation. This equipment has obtained multiple intellectual patents, such as: "Continuous Flow Pipeline-type Wastewater Catalytic Treatment System ZL202221041471.3", "Pipeline-type Ozone Composite Thermal Fenton Reactor 2022107684980" and "Hydrogen Peroxide Synergistic Ozone Catalytic Wet Oxidation Reaction System ZL202122801385.X". The equipment has high oxidation efficiency, no risk of secondary pollution, fast reaction speed and high integration level.

: Peaction Principle

The metal ions are immobilized as a solid-phase catalyst, primarily catalyzing the generation of free radicals from hydrogen peroxide. Concurrently, a small amount of dissolved initiator is added to enhance the catalyst's electron transfer capability, reduce catalyst consumption, and prolong its service life.

: Stable Effect

The main reaction takes place in a tubular reactor. The reactor has a small diameter, a large length-to-diameter ratio, and little backmixing, approaching plug flow. The oxidant concentration parameters at the same position are constant, and the reaction effect is stable.

: Fast Reaction Speed

The radial mixing speed of wastewater and oxidant in the pipeline is extremely fast (reaching the second level), which can significantly shorten the reaction time, reduce the ineffective decomposition of hydrogen peroxide, and realize the high efficiency and integration of equipment.

: Spiral Plate Heat Exchanger

The spiral plate heat exchanger is fabricated from a single rolled plate, featuring no welding or damage, with strong corrosion and scaling resistance. It is suitable for media with high solid content, and its 5mm flow width maximizes the utilization of steam latent heat. The temperature difference between inlet and outlet water is less than 20°C.

Reduce Costs

Compared with the traditional Fenton process, the addition of iron salts is reduced by over 90% when using the self-developed high-efficiency catalyst, while the production of iron sludge is correspondingly decreased.
Improving the Utilization Rate of Hydrogen Peroxide

Radical oxidation reaction, reducing the ineffective decomposition of hydrogen peroxide and improving the utilization rate of hydrogen peroxide
Rich Application Scenarios

Compared with traditional Fenton technology, this technology has a wide range of requirements for the initial pH of wastewater. Moreover, it can not only be used to remove COD from wastewater but also has the function of cyanide breaking.
Easy to Manage with Integrated Devices

The oxidation reaction in the pipeline reactor typically concludes within 2 minutes, enabling equipment integration with minimal floor space requirements. Automated control facilitates easy management.
